Feature Request: Native Process Forking for Parallel Context Exploration

The Problem

When working on complex tasks, I frequently hit situations where I need to explore multiple directions simultaneously - but context is a single thread that can only be in one place at a time.

Example scenario: While building a new feature, I want to:

1. Continue implementing the main logic
2. Explore how a similar pattern was solved elsewhere in the codebase
3. Check if my changes will break existing tests

Currently, I can spawn subagents via the Task tool, but they:

• Don't share state cleanly with the parent
• Can't be truly parallelized (I wait for results or poll)
• Lose context richness when summarizing back

The Request

Native process forking - the ability to split context into parallel branches that:

1. Share memory - both forks see the same conversation history up to the fork point
2. Execute concurrently - actual parallel work, not sequential with message passing
3. Merge gracefully - bring insights from branches back together with conflict resolution

Proposed UX

/fork "explore auth patterns" "continue implementation"

Creates two parallel contexts. Each runs independently. Parent can check on children, children can signal completion, and results merge back.

Why This Matters

LLMs naturally want to explore multiple hypotheses. The current single-threaded model forces artificial serialization of thought. Forking would let agents work the way they think - following multiple threads and synthesizing.

The subagent system is a great stepping stone, but true forking would be transformative for complex agentic work.
